The molar conductance of acetic acid at ...

The molar conductance of acetic acid at infinite dilution if `Lambda^@` for `CH_3 COONa,NACI` and ` HCI` are `91.0, 126.5` and `426.2 S cm^2 "mol"^(-1)` respectively is :

A

`517.2`

B

`552.7`

C

`390.7`

D

`217.5`

Text Solution

Verified by Experts

The correct Answer is:
C
`Lambda_(CH_(3)COOH)^(@) = Lambda_(CH_(3)COOHNa)^(@) + Lambda_(HCl)^(@) - Lambda_(NaCl)^(@)`
`= 91.0 + 426.2 - 126.5`
`= 390.7 S cm^(2) mol^(-1)`
